Application led December 5, 1910. Serial No; 595,611.

To all 'whom it may concern:

.Be it known that I, AXEL JOHNSON, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Can-End- Flanging Mechanism, of which the following is a specilication.

The invention relates to'an improved apparatus for Hanging .the ends of cylindrical can bodies to prepare the same to receive and have seamed thereto the can ends or y heads, the object oit the invention being to dispense with the use of the Hanging rolls and associated spinning mechanism `com monly employed for Hanging over the ends of the can bodies, and to provide an automatic end Hanging machine of a simple, effective and durable construction for use in can making factories for Hanging can bodies prior to receiving an end or head and in canning factories for Hanging the end of fill d cans to which heads are to be applied an` by means of which the ends of the can lbodies may be Hanged by a single operation ofta reciprocating Hanging plunger die movable toward and'from the open end of a retained or clamped can body, the said reciprocating Hanger die acting against the linner wall surface of the can end to be flanged and gradually turning over or Hanging outwardly the entire circumferential end ot' the body as a single operation.

The Hanging mechanism comprises a cofurnishedwith a plurality of Hanging dies, a longitudinally reciproca-ting Hangin die which registers successively with the anging. dies of the rotary carrier, a vertically re- 491ciprocating' Hanging plunger die, and means for imparting an intermittent movement to the rotary carrier and successively throwing into action the reciprocating Hanging die and the' vertically reciprocating Hanging x plunger die.

In the accompanying drawings to which reference is hereto made-Figure 1 islaf-side elevation of the improved can end Hanger, illustrating the various parts in normal position, and disclosing the drive mechanism for actuating the rotary, carrier and the connections for operating the reciprocating Hanging die and the Hang-ing plunger die. Fig. 2

Fig. 3 is a part sectional side elevation of the' parts disclosed by Fig.

2 of the drawings. Fig. 4 is a detail view of the adjusting means for regulating -the throw of the Hanging plunger die. `F ig. 5

is an enlarged detail part sectional `view illustrating the segmental Hanging dies in` registry, a can body held therein, and the position of the plunger die after having Hanged the end of the can body. Fig. 6 is a detail view of the cam grooved disks for controlling the action of the reciprocating segmental Hanging die and the reciprocating Hanging plunger die.

In the drawings, the numeral l represents the frame of the machine, the same being of any suitable form capable of giving support tothe other parts. Through this frame extends the vertical shaft 2, carrying at its upper end au intermittently rotating carrier 3 provided with a plurality of upwardly extended segmental external can Hanging dies 4, each of which is adapted to partly embrace a can body 5.

The shaft 2 supporting the rotary carrier 3 is extended through a sleeve 6 situated Iwithin the frame of the machine and adjacent its lower end has secured thenecn a radially slotted wheel 7, which is intermittently driven by an engaging roll 8 carried by and depending from a gear 9. This gear is mounted on an upright shaft l0, drlven from the -main drive shaft 11 through the medium of the intermeshing bevel gears 12 and 12', the former of which is on the main drive shaft 11 and the latter on the upright shaft 10. Under this construction an intermittent or Geneva stop movement is thus imparted to the shaft 2 and carrier 3 from the main drive shaft 11.

The gear 9 meshe's with a gear 13 carried by the lower end portion of the sleeve 6 forI transmitting continuous movement to thel said sleeve and the parts carried thereby.

Each of the segmental Hanging dies 4 of the rotary carrier 3 is provided or furnished with an'upwardly .extended segmental wall extension 14, which in conjunction with a similar wall extension 14 of the longitudiweones V'y reciproc'ating` segmental dangling die o ervsl when tbe iianging dies are in registry, as a guide extension of the Hanging dies for the vertieally reciprocating' plunger die lo, and into ivliieli guide exten sion tlie end of tbe can body to be flanged projects.

The neciprocating` segmental Hanging die 15 is secured te slide 1i Working through a guide 17 on. the Jrame or" the machine., and

this slide is connected to an operating tulcruined lever 1S by a link 1S". ln order 'iat the ianging die may move into perfect registry with the segmental dies el, ille saine 15 is provided with tlie projecting lugs or tongues 15 ivliicli move into engagement with the countfeisunl seats si in tlie face of' each or' the ilanpjing; dies il.

Above tbe rotary carrier 3 and in aline- 26 nv eut with the segmental Hanging dies and 15 when in registry is held a vertically reciprocating Hanging plunger die lG, the stern 16 of which Works tlirouggl'i guides 1"? sustained by tlie overhang' portion of a acliet or standard 19 upwardly proyecting from tbe machine frane, and the said nlnnger die is raised and lowered by means of lever 182 `tnlcrumed to the said standard if?. This lever at one end is pivoted to tlie 3o plonger stem 1G and at its opposite end se* cured by the toggle link Connections 20 and 2l to the adjustable screw-threaded nos 29., the said connection beim; in turn connectedl to 'tbe .tulerumed operating lever 23 by the link connection 23. 'lllie nos" extends 'througli the guide shelf 22 and` is raised and lowered by the adjust-ing nuts 2 and 25, which Work against the upper and ioiver faces of the shelf Q2. 4o The sleeve G is a continuously rotating" one and on the same is secured the spl ced isles 2S and 2G and to properly tlnow tbe rec ro-eating VYang,ing die 15 and the Hanging; rplunzgfer die 16 Aand thus cause each ot tbe id dies to be propeiiy reciproeated in unison with the intermittently rotary carrier il, which carries the Hanging dies il, at eacli stop or period of rest of the carrier 3, there is provided for the fulcrnmed levers 1S and -o 'z3 tlie operatingI links 27 and 27', Wliicli at their 'rce ends carry the rolls @Send The roll 2,8 Works witlnn an 'irregular carri groove 2711 out in the under i'ace ot' "die ci?

The can/ bodies 5 to be flanged, are delivered in any suitable manner ontd the rotatable carrier 3 and Wi liin tlie segmental 5b Hangingy dies 4, so tliat (fie end tio/be dang" l projects a slight. distance abmetl/e lano'nr; surface or edge'tz and a et the tiene; g dies i and l15 when in registry. is tbe bori- Zontally intefijlinittent-ly rotary carrier prrr pels the can Ybodles toward the i'iangingi mechanism, the said bodies are held 'Within the segmental Ranging dies 4 by the seg mental fue d lite 2.9, Wliioli partly encircles the rot -rarrier 3. When the held een body is i alinement- With the langing plunger di 16, the carrier comes to a state of rest, and during suoli pause in the rotation ofthe rotary carrier 3 the rotary ino tion of the disli: 2&3 through the described connection throws inwardly the reciprocating slide l? carrying the :Hanging die 15 tov 'place tlie in registry 'with the Hanging die ll, when the movement of tbe disk 26i is cumterential slioulderz-id portion of the die 16 finally acting to compress the can lange 2'/ onto the dangling surfaces a 'and e of the registered .Hanging dies. After tbe end ot the clamped can has been flanged the rotary movement oli tbe disk 26,` through the medium of the roll 28 Working in the cani groove 27h ol' the said disk, ,imparts motion to the link 27 to draw inwardly tbe lower end of the ulcr-umed lever 23, throwing,` outwardly its upper end thereof and torougli the describedconnections actuating lthe tulorumed lever 182 to thi-ovv upwardly vits inner end for lifting' the vertically movfrom Within vthe guide extension tbe reg-Y istering segmental llanging; it the une time tbe movement. ol the disir will impart a reverse action to the connections tor actuatingl the slide 1.7, Causing the dang- 'ing` die .15 to move away from the tlang'ing 4f, by which time the roll 8 of tbe gear 9 f ll actuele tbe radially slotted Wheel l to ninart a step rotation to tlie carrier 3 for taking tlie flanged can body from Within tra sphere of the iianging plunger die and advancing an unilanged can body beneath tbe same.

"lo permit of the reciprocating Hanging' ima ein

die to move into registry vvitli the langing die fr without iiiterrerence Witli'tlie segnmntai juard plate 29, the said .tianging die 15 is slotted at transversely in order to nenn-,it of the die straddlng the segmental guard plate 29 as moved inwardly.

' By providing for an adjustment to the post 22 the throw of the plunger Hanging die 16 may be varied to accommodate the sti t 'lli roof to can bodies to be flanged.

'tlie reciprocating internal plunger die lo acts on tlie entire Surface of the end to be anoY and by so doingl turns over the metal at af single operation, thus overcfming the splitting of the end metal which follows 4from the employment of Hanging rollers which act successively against small sections of the circumferential wall of the projectin end to be Hanged.

The working of the various parts of the apparatus is entirely automatic, and the working of the associated parts sotimed'as to come into action at the proper moment.
